2 Review of Literature: Motorcycle helmet

this modification weakens the structural integrity of the helmet and does not comply
with safety standards. Thus, the safety and protection of the head are substantially
reduced. This approach requires a major modification to current helmets to make
use of the conceptual ideas. The alterations made to the helmet void the helmet
with respect to regulatory requirements, making the use of helmet unacceptable. In
addition, this concept study adds many components to the helmet, and as such, it
will incur in additional manufacturing cost. The end result of following this concept
results in a new helmet design to incorporate the concepts with additional compliance
tests that were required to meet the safety standards.
Heat transfer phenomenon and cooling of different types of ventilated helmets
have been conducted by several researchers [17, 34, 50]. Ellis et al. [260] conducted
research on bicycle helmets with a view to improving their performance. To the best
of our knowledge, very few of these works have involved the heat stress reduction of
motorcycle helmets. The work done by Ellis did not address non-ventilated helmet
